Ability to change Json boolean colors

I want to display true and false values of a boolean json object in different collors: when true, it must be green. If false, it must be red. How could I do this?

Reading source code, I've noticed that here, true, false and null values are threated as Keyword.Constant keywords. So, I think that because of this, it is impossible to make a custom colorscheme mapping in TerminalFormatter for each boolean situation. Am I right?
